Bonsoir tout le monde j aurais besoin d'aide Lors d'un contrôle technique, on étudie le freinage d'une voiture de poids P= 9,6 kN. La force de freinage totale (avant et arrière) mesurée vaut F= 8,92 kN. 1. Quelles sont les forces qui s'appliquent sur la voiture ? Les schématiser à l'échelle. 2. Donner les caractéristiques de la résultante des forces. 3. Calculer la variation de vitesse de la voiture en 1 seconde lors du freinage en m·s-1 puis en km·h-1.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
